1 Introduction
Congratulations on your purchase of a Digital Subscriber Line (DSL)
modem.The DSL Modem is part of a system that provides an
integrated end-to-end solution for data connectivity, multimedia
services, and high-speed Internet access services using an
asymmetrical digital subscriber line (ADSL) transmission over your
current telephone wiring.With ADSL technology, information can be
processed at speeds up to 250 times faster than today’s analog
modems.
1.1 ADSLTechnology
As the interest in telecommuting and the Internet grows, the search
for methods of delivering larger amounts of data over the existing
copper telephone wire increases.ADSL technology is one method of
delivery.
ADSL technology uses advanced digital modulation to transmit data
at high speeds over standard telephone wiring.This technology can
download data at 8 Mbps and upload data at up to 768 kb/s.
The DSL Modem is part of a system that enables Internet service
providers and local telephone companies to offer high-speed Internet
access, virtual private networks (VPNs), telecommuting, video on
demand, and other broadband services.

To benefit from the high-speed transmission rate of ADSL over your
existing telephone wire, your phone line and your computer must be
separated. Each DSL line must be wired through a special filter
called a splitter.While both the DSL Modem and the telephone share
a telephone line to the customer premises, the signals are separated
at the splitter, providing an isolated path to the individual wiring,
jacks, and other telecommunications hardware.This splitter is
installed by the telephone service provider.
With the use of a DSL Modem, splitter, and your existing telephone
line, you can use the telephone and download data onto your
computer at the same time.The DSL Modem splitter is completely
passive, providing “lifeline” or continuous, telephone service even if
the power fails.The DSL Modem encodes the data sent from your PC
to a corresponding DSL Modem, located at your local telephone
company.
1.2 Unpacking Instructions

3 Connecting the DSL Modem to the Splitter
3.1 Overview
Note: The procedures in Section 3 only apply to those customers who
choose to wire their own splitter-to-modem connection.If a certified
technican is performing the wiring, then proceed to Section 4 Turn-Up
and Operation.
The network interface device (NID) is typically located on the outside
of the customer premises. Certain installations, such as those at an
apartment complex, require the splitter to be installed closer to the
DSL Modem.The telephone or ADSL service provider also installs
this type of splitter.
Note: The telephone service provider will install a splitter in the
network interface device (NID) to separate the voice and data interior
wire paths.
Before connecting the wires from the NID to the DSL Modem, verify
that the inside wire pair serving the DSL Modem has an isolated
path from the NID to the modem. Do not connect a telephone to the
same wire pair. In some instances,it may be necessary to reroute the
inside wire away from noise sources such as appliances, fluorescent
lighting, televisions, light dimmers, and other electrical noise
sources. It is recommended that the modem has dedicated inside
wiring.
For the DSL Modem, you will only need to connect the wires
associated with data output on the NID.The telephone company
technician has already connected the voice (or telephone) wiring.The
data module provides a connection point for the inside wire pair
serving the DSL Modem.
Note: Category 3 (CAT 3) or Category 5 (CAT 5) twisted-pair wire is
recommended.
For inside wiring procedures see Section 3.2 before you start.

3.2 InsideWiring Procedures
WARNING:
Interior home wire is the homeowner responsibility.The following wiring
diagrams represent a standard wiring scheme.Not all homes will follow
this convention.Standard telephone company inside wire coverage
options will not cover the cost to repair voice path problems that may
arise as a result of homeowner wiring attempts.These repairs may be
billed to homeowner as regular time and materials repair charges.It is
recommended that all ADSL inside wiring be performed by a certified
technician.
If you are using original inside wire, then see the section Spare
Inside Wire. If you are using new inside wire cable (CAT 3 or CAT 5)
for the data, then see the section New Inside Wire.
See Figure 3-1 for a diagram of the NID data and voice outputs.
Note: From the NID, open the latch door to the data module.You will
see four colored screws.Note the coloring of the wire that is connected
to the green and red screws.For this installation, you will only need to
connect the wires associated with the data output.The telephone
company technician has already connected the voice wiring.
